What Causes High-Speed Vibration in Cars?
2 Answers
High-speed vibration in cars is mostly due to issues with wheel dynamic balance. Here is some information about wheel dynamic balance: 1. Main Causes: A car wheel is an assembly consisting of a tire and a rim. Due to manufacturing factors, the mass distribution of this assembly is not uniform, leading to dynamic imbalance when the wheel rotates at high speeds. This results in noticeable steering wheel vibration felt by the driver. 2. Solutions: The most effective method is to add counterweights to the wheel under dynamic conditions to correct the balance at various edge positions. 3. Other Causes: Faulty shock absorbers, frame deformation, excessive backlash between the drive and driven gears of the main reducer, etc. 4. Solutions: Regular dynamic balance checks for the wheels.
I've noticed many cars shake violently on the highway, and the most common cause is tire imbalance. If you don't pay attention to tire maintenance in daily driving—like not getting regular wheel balancing or having incorrect tire pressure—the wheels rotate unevenly during high-speed turns, causing the car body to wobble. Uneven tire wear or bulges can also lead to this. I want to remind everyone: after changing tires, always check the balance, and inspect tire conditions every six months. Don’t skimp on this—shaking isn’t just uncomfortable, it can easily lead to loss of control. Get it fixed at a repair shop early. I once experienced severe shaking myself, but after replacing the tires and balancing them, the car became rock-steady at high speeds.
